Insights and Findings

Canada

The Canadian population has seen a significant shift in demographics since the 2016 census. Millennials in Canada are the fastest growing age cohort in the country, between 2016 and 2021 the millennial population increased 8.6%. These increases were mainly due to immigration. Millennials in Canada (born between 1981 and 1996) now account for 33.2% of the working-age population (15 to 64 years old).

Ageing baby boomers (55 to 74 years old) currently make up 24.9% of the Canadian population.  Those 85 and older continue to be a fast-growing age cohort – in the 2021 census, 861,000 were counted, representing 2.3% of the population. By 2046 it is expected that those over the age of 85 could total 2.5 million people. A significant proportion of this age cohort have activity limitations or health-related issues with more than one quarter in collective dwellings, nursing care facilities, and long-term care homes. As more of our population continues to age beyond 85 years old, limitations around long-term health will put increasing challenges on all levels of government, primarily in housing, transportation, and healthcare.

Ontario

Millennials continue to dominate large urban centres across the country accounting for more than 35% of downtown populations, while baby boomers represent 20.9%. Millennials living downtown are primarily made up of postsecondary students and young working professionals. This age cohort now outnumbers baby boomers in Canadas six largest urban centres. Toronto millennials account for 40% of the city’s total population. People aged 85 years and older are highly concentrated within large urban centers in Quebec, Ontario and British Columbia. Ontario cities such as Peterborough, St. Catherines, Niagara, Kingston, Hamilton, Greater Sudbury, Brantford, Windsor, London, and Guelph all had higher proportions of those aged 85 years and older.

York Region 

York Region’s demographics are following a similar trend to that of the country. Baby boomers within York Region have increased 18% since the 2016 census to account for 283,325 residents in 2021. Millennials make up 18% of the Region’s total population with an increase of more than18,665 residents since 2016. Millennials within York Region now account for 27% of the Region’s working-age population (15 to 64 years old).
